SPECIFICATION forming part of Letters Patent No. 435,891, datedSeptember 2, 1890.

Application filed January 25, 1890. Serial No. 338,085- (No model.)

To all whom it may concern:

Be it known that I, NATHANIEL 0. GOLD- SMITH, a citizen of the UnitedStates, residing at Cincinnati, in the county of Hamilton and State ofOhio, have invented certain new and useful Improvements in Coke-DrawingMachines, of which the following is a specification.

My invention relates to a new and improved device for drawing coke outof ovens. It comprises a driving device operated by an engine,preferably mounted upon a car which can be run back and forth in frontof the oven,having an oscillating table upon which are mounted theguides for the reciprocating arm carrying the pulling-claws, withsuitable mechanism for stopping, starting, tilting, and swinging thereciprocating claw-arm in a horizontal and in vertical plan es, all ofwhich is done with power furnished by the boiler.

The description of the accompanying drawings makes a part of thisspecification, in which- Figure 1 is a side elevation, part of the framebeing broken away to show the operating mechanism. Fig. 2 is a top planview. Fig. 3 is a view, partly in section and partly in elevation,showing more especially that part of the mechanism which raises andlowers the rake-arm. Fig. 4 is a plan view of the same, and Fig. 5 is aside elevation of the steam and fluid cylinders of the same. Fig. (3 isan end view, partly in section, showing the rake-arnrholdin g mechanism.Figs. 7 and 8 are details of the same. Fig. 9 is an end view in oppositedirection from that of Fig. 0; and Fig. 10 is a section through line a;as, Fig. 2, looking to the left. Fig. 11 is a detail view of the clutchmechanism for throwing the rake mechanism out of gear. Fig. 12 is acentral vertical sectional view of the steampiston valve, showing thepistons at one-half stroke. Fig. 13 is a similar view showing thepistons at the limit of the downstroke. Fig.

5 14 is a similar view showing the pistons at the limit of theirupstroke. Fig. 15 is a detail broken perspective view of the clutchmechanism for effecting the lateral swing of the rake.

The same letters and numbers on the different sheets of the drawingsrefer to similar parts of the mechanism.

which passes through turn-tables 64 and 65, and also through thehorizontally-oscillating table T,'and has at its upper end abevel-pinion W, which is fastened to it. Pinion W meshes with abevel-gear X, which is keyed to the shaft Y, which has bearings 16fastened to the oscillating table T. Z represents a gear keyed to shaftY and meshing in rack 42 on rake-arm 41. On the oscillating table T isalso fastened a frame 15, which supports a steam-cylinder 1 and twofluid-cylinders 2.

(See Fig.- 3.) The steam-cylinder 1 is connected to the valve 0 by meansof flexible c taps the upper end of the steam-cylinder 1 and d taps thelower end of said cylinder. The upper and lower ends of 'theflu'id-cylinders 2 are connected by means of pipes 4,'in which is placeda (Shown in Figs. 1 and 5.) The steam-cylinder 1 has a piston-rod 5, theupper end of which is attached to the pistonrods 6 of the fluid-cylinderby means of the yoke 7, and on the lower end is. fastened a yoked frame31, as shown in Fig. 3. On the piston-rod is also the piston 29, slidingin the steam-cylinderl. The piston-rods 6 have pistons sliding in thefluid-cylinders 2.

The valve O, which has a connection 38 with the boiler A, contains twopistons 37, fastened to the stem 34. These pistons 37 have ports 36,Figs. 3, 12, 13, and 14, through which the steam is free to pass.

On the opposite end of the yokedarm 59 is a bevel-face, which fits the bevel-face 62 of the treadle t.The yoked arm 59 moves the friction-clutch 67 along the shaft 57 whenthe treadle t is pressed to the left. Between the turn-table 64, whichis bolted to oscillating table T, and turn-table 65, which is fastenedto the frame F, are rollers 10. (Shown in Figs. 2 and 6.) These rollersrevolve on the pins 71 and support the oscillating table T at one end.

19 represents a tram-guide rail fastened to the frame F, upon which runwheels 20, revolving on axles 21, which are attached to the table T.

17 represents rubber bumpers, one of which is attached to the table Tand the other to the frame. 15, (shown in Fig. 3,) which are cushionsagainst which the yoked frame 31 strikes to limit the upward or downwardmovement of frame 31.

25 represents a curved rack bolted to the oscillating table T. (Shown inFig. 2.)

23 represents a spur-wheel meshing in the rack 25 and keyed to the shaft24, on which is also keyed a worm-wheel 22, which meshes with the worm26, which is fastened to shaft 27, to which the chain-wheel 28 is alsofastened. The shaft 24 and also shaft 27 have bearings which areattached to the frame F. (Shown in Figs. 2 and 6.) The chain-wheel 28 isconnected to the chain-Wheel 18 by means of chain 72, as shown in Fig.2.

In Fig. 6, 41 represents the rake-arm, on the upper side of which isattached a rack 42, and at one end is attached the pullingclaws by meansof the bracket 49.

On the shaft Y are two frames 46, which are free tooscillate and whichcarry the guiderollers 47 and 48, which revolve on pins 73 and 74. Theseguide-rollers 47 and 48 form anti-friction journals for the rake-arm 41and allow it to move freely back and forth. It can be swung in aVertical plane, because the frames 46 can turn on shaft Y. These rollersare shown in section in Fig.8. To the yoked frame 31 are attached, bymeans of the stud 68, the frames 43.

44 and 45 represent guide-rollers, which are free to revolve on the pins75 and 76, which are attached to the frame 43, and which IIO also allowthe rake-arm 41 to move freely back and forth and to move in a verticalplane, the frames 43 and 4:6 oscillating on their respective journals.The yoked frame 31 has guides 33, (shown in Figs. 3 and 6,) which movevertically on the rods 32, which are supported by the frame 15 and theoscillating table T.

Mode of operation: By looking at Fig. 1 it will be seen that by throwingthe lever L to the left the chain-wheel I will be locked to the clutchII by means of the friction-clutch faces. This will allow the operatorto drive the worm Q and revolve the axle 14 by means of the worm-wheelR, and move the machine back and forth on the track 1' by means of thereversing-lever 77, which arranges the valves of the engine E so thatthe crank-shaft K shall revolve in either one direction or the other. Ithus provide a self-propelling machine, and at the same time the worm Qlocks the wheel R and keeps the machine from moving when the pressure ofthe rake 011 the coke would tend to move the machine on the track-railsr. If, on the contrary, he throws the handle L to the right the clutch Hbecomes disengaged from the chain-wheel I and is locked to the pinion Gby means of the clutch-face, and when the shaft K revolves thespur-pinion G drives the transmittinggear h, which in turn drives thegear S, which revolves the shaft 57 and turns the bevelpinion U, thebevel-wheel V, the shaft 11, the bevel-pinion IV, and the bevel-wheel X,the shaft Y, and the spur-wheel Z, which moves the rake-arm 41 by meansof the rack 42. This will run the rake-arm 41 into the oven; but byreversing the engine, by means of 18V61'77, the direction of themovement of the rakearm will be reversed and it will come out of theoven. By throwing the lever 8, Fig. 10, to the left the pistons 37 inthe valve 0, Fig. 3, are raised. The lower valve opens the exhaust-port35 to the lower end of the steamcylinder 1, and the upper valve opensport 36 and allows the steam to pass from the steamport 38 into thesteam-pipe c, admitting the steam into the top of the steam-cylinder 1.This forces the piston-rod 5 down and forces the fluid from the bottomof the fluid-cylinders 2 through the connecting-pipet and thethrottle-vale 3 into the top of the fluid-cylinders 2, the valve 3affording the means of regulating the speed at which the piston-rod 5travels. Inasmuch as the piston-rod 5 is attached to the yoked frame 31,it will be seen in Fig. 6 that when the pistomrod 5 is pushed down theend of the rake-arm 41, to which the pulling-claws 50 are attached, willbe raised, swinging on the shaft Y. hen the lever 8, Fig. 10, is pulledto the right, (or toward the operator,) however, the pistons 37, Fig. 3,will be pulled down, and the steam from the upperend of the cylinder 1is free to pass through the steam-pipe 0 into the exhaust-opening 35,while at the same time steam. will be admitted through the lowersteam-port and the steam-pipe d into the lower end of the steamcylinder1, raising the piston 29 and the piston-rod 5, and forcing the fluidfrom the top of the cylinders 2 into the bottom and lowering thepulling-claws 50,Fig. 6. This arrangement affords a means of raising thepullingclaws of the rake-arm above the coke when the rake-arm is passinginto the oven, and forcing it down on the coke when the rakearm ispassing out of the oven. hen it is desired to swing the rake-arm toright or left while it is being reciprocated, the foot-treadle t ismoved to the left in Fig. 10, and the yoked arm 59 is thereby. moved tothe right in Fig. 2, forcing the friction-clutch 67 into the chainwheel18, and causing the same to revolve with the shaft 57. This motion ofthe treadle compresses the spring 58, and as soon as the treadle isreleased the spring forces it back into its natural position, releasingthe clutch and stopping the lateral swinging movement of the rake-arm.\Vhile the treadle is pushed to the right, however, and while the shaft57 is revolving, the chain-wheel l8 revolves the chain-wheel 28 by meansof the chain 72, and turns the shaft 27 and the worm 26, the wormwheel22, and the gear 23 by means of the shaft 24, and swings the table T tothe right or to the left by means of the rack 25. It will be seen thatthis table rides on the wheels 20, traveling on the rail 19. (See Fig.2.) Said table is pivoted at the opposite end by the shaft 11, andsupported on the conical rollers 10,which bear on the turn-table faces04 and and allow it to swivel freely. Inasmuch as all the guides andbearings for the rakearm 41 are attached to this oscillating table T, itwill'be observed that the rake-arm can move in a horizontal plane, andby regulating the time which the foot-treadle is pressed thepulling-claw 50 can be swung from side to side in any part of the oven.This gives the operator complete control of the rake by means of thereversing-lever 77, which controls the means of moving the rake back andforth, and the lever 8, which controls the raising and loweringmechanism, and the foottreadle t, which controls the mechanism formoving the rake horizontally, and allows him to operate the rake veryrapidly and easily.

In Fig. 11 is shown a modification in the mechanism for propelling therake backward and forward. It will be noticed that, as heretoforedescribed, the chain-wheels 18 and 2S and mechanism for oscillatingtable T could only be operated while the gear U, and consequently therake, was in motion. The modification in Fig. 11 provides for theoperation of chain-wheels 18 and 28 while the gear U remains idle, andis a representation of that part of shaft 57 which lies to the right ofchaiirwheel 18. F represents the frame in which the shaft is mounted;57, the shaft; U, the gear\vheel; a, a boxing secured to frame F, inwhich revolves a hollow sleeve m, through which passes the shaft 57. Thewheel U is secured to one end of sleeve m, and to the IIO - vicessubstantially the same as used to operate the clutch 67, Fig. 15, is notmore fully illustrated. By means of this device the gear U may be throwninto and out of engagement with the shaft 57 and the table T swungindependently from the backward and forward movement of the rake.

The object of my invention is to provide a rake operated by steam-powerand so arranged that the rake may have a motion in a vertical andhorizontal plane and move in any position without producing any strainon the different parts of the machine which will tend to interfere withtheir moving freely.

In respect to the motion of the rake in and out of the oven it will beseen that the planetary system of gears, including bevel-pinion U,bevel-gear V, bevel-pinion WV, and bevelgear X, allows the gear Z on theshaft Y to always occupy a position. at right angles to the rack 42 onthe rake-arm 41, and by this means there is no position in a horizontalplane limited by the motion of the table T in which the rake-arm 41cannot be driven in and out of the oven.

I have shown the mechanism here described as adapted to be moved by theoperator seated on seat 9, who manipulates the levers to get the variousdesired movements. As the rake has to beinserted into the oven tovarying distances in the operation of pulling the coke, and as the rakeis driven by steam and controlled by admitting and cutting off thesteam, I avoid the use of Windlass and ropes for reciprocating therake-arm.

I believe I am the first to provide amachine which will control theoperation of the rake and the pulling device by manipulation of thelevers for controlling the different rake movements vertically andhorizontally as well as controlling the'length of the stroke.

The fluid-cylinders 2 are merely to regulate the speed at which thepiston-rod 5 travels, either up or down, and this speed can becontrolled by the opening in the throttle-valve 3, allowing a greater orless quantity of fluid to pass through it.

The steam-pipes c and d are made flexible so that the steam may alwayspass into the steam-cylinder 1, in whatever position the oscillatingtable T may occupy.

I do not confine myself to the specific con- I struction or arrangementof parts shown by the drawings. The piston steamvalve 0, the threecylinder-engines E, the desired arrangement of parts to make the machinea self-propelling one, and the arrangement of parts to move the table Tback and forth in ahorizontal plane can be variously modified withoutinterfering with the utility and successful working of the machine andstill present the principal features of my invention.
